REFRIGnnATING APPARATUS.

Application led October 28, 1927. Serial No. 229,366.

This invention relates to refrigeration devices and has for an object to provide a plurality of circulating `coils disposed in pa'rallel with respect to a series of fines, the coils being adapted lfor the passage of a cooling fluid therethrough whereby to cause a lowering of the temperature within the fines and thus create a circulation of the air within the refrigerating compartment and which will be maintained at a desired uniform temperature by reason of its contact with the coils.

A further object of the invention is to provide a plurality of refrigerating units within a compartment and composed of a series of flues inclined in a direction toward a common point in the compartment at which time the cooler air from the flues is discharged andA which upon coming into contact with the warmer airin the compartment remote from the refrigerating devices, operates to cause a circulation of the air so that the entire volume thereof will from time to time come into contact with the refrigerating unit and thus lower the temperature of the same.

A still further object is to provide an apparatus of this character of simple and practical construction, etiicient and reliable in performance, economicalin operation, inexpensive to manufacture and install and otherwise well adapted for the purpose for which the same is intended.

Other objects and advantages reside in the yspecial construction and combination of the various elements comprising the invention, reference being had to the accompanying drawings forming a part hereof, wherein Figure 1 is a vertical sectional view through a refrigerating compartment equipped with a pair of refrigerating units constructed in accordancewith our invention Figure 2 is a horizontal sectional view taken Substantially along line 2 2 of Figure 1 rFigure 3 is a similar view taken substantially along the line 3-3 of Fie'ure 1 and showing the bottom plan view ofj one of the division plates lforming* one of the flues,

Figure 4 is a vertical transverse sectional view taken along the line 4--4 of Figure 1 and Figure 5 is a perspective view of one of the division plates.

Referring now to the drawings in detail, we have shown our invention adapted for use in connection with a refrigerating compartment indicated at 5 which may be of any suitable shape or construetiom the top ot' which, at its inner side is provided with a plurality of transversely extending beams 6 forming a support for the downwardly extending refrigerator unitsupportingY rods 7. These rods constitute supporting means for the series 'of division plates 8 of a rectangular formation having each corner notched' as at 9 forming a seat for the rod whereby upon engagement therewith to prevent longitudinal or transverse movement of the plate within the compartment.

The division plates are arranged in spaced parallel relation at anlinclined angle from a horizontal plane as more clearly illust-rated in Figure 1 of the drawings, the space between the plates constituting a flue and arranged wit-h the discharge end of each unit contained within the compartment extending toward the center of the compartment.

A section of pipe coil 1() is arranged within each of these flues and disposed in the upper portion thereof adjacent thc underside of the division plates forming the top of the liuc` the pipe section forming the coil eX- tending in spaced parallel relation at right angles to the direction of travel of air through the flue. The ends of the coil of each tlue are connected by vertical sections 11 to each adjacent section of coil immediately above and beneath the same.

The coil at the lowermost flue of one of the refrigerating units is connected by a pipe 12 extending to the coil of the uppermost flue of the adjacent refrigerating unit. An intake pipe 13 is connected to the coil atthe uppermost flue of one of the refrigerating units, said intake pipe having a control valve 14 interposed therein and the lowermost coil of the opposite refrigerating unit is connected by a discharge pipe 14 leading from the compartment.

It will be apparent that upon feeding a cooling fluid into the intake pipe 13 that the passage of the same through the coil section 10 arranged within the flue will thereby have a tendency to cool the air through the llues, which upon being cooled will have a tendency to iiow downwardly through the ues toward the center of the refrigerating compartment. The cool air from the lues, coming into contact with the relatively warmer air at the center of the compartment will cause the warm air to move upwardly to- Ward the top of the compartment, the suction of the air traveling through the flues thus causing the Warm air at the top-of the compartment to be drawn toward the intake end of the fines whereupon during the continuous operation of the device the air throughout the compartment will eventually become uniformly cooled to a relatively low temperature.

The feeding of the cooling liquid into the coil may be controlled in any suitable manner as by means of the manually operable valve 14 o`r in any other suitable manner depending upon the particular condition under which the apparatus is operated.

It will be understood that while the present disclosure of the invention shows a rerigerating compartment equipped with two of the refrigerating units constructed in accordance with my invention, any suitable number of these units may be installed within the compartment to meet particular conditions.

It is obvious that the invention is sus-l ceptible of various changes and modifica.- tions, Without departing #from the spirit or scope of the invention or sacrilicing any ot' its advantages, and we accordingly claim all such forms of the device to which we are entitled.

Having thus described our invention,

what we claim as new is:

extending toward a common point within the compartment and a pipe coil arranged with each of said lues.

2. In a refrigerating apparatus of the class described, a retrigerating compartment and a plurality of refrigerating units arranged therein, each of said units being formed of a plurality of division plates arranged in spaced parallel relation and constituting lues with vtheir side edges spaced from the walls of the compartment whereby to permit the free circulation oit air entirely about each flue and with the lower ends thereof extending toward a common center ot the compartment and a pipe coil arranged Within each of said lines.

3. In a refrigerating apparatus of the class described, a refrigerating compartment and a plurality ot' refrigerating units suspended in the compartment and formed ot' a plurality of division plates arranged with their side edges in spaced relation from the walls of the compartment and in spaced parallel relation with respect to each other whereby to prevent the tree circulation of air entirely about each of said plates, said lates being `further angularly disposed trom a horizontal plane, the space between each of said division plates constituting Hues having their lower ends extending toward a common point within the compartment, a pipe coil arranged within the upper portion of each ot the lines, the coils of each flue being connected with each other and means connecting the coils of the respective units.

In testimony whereof we aliix our signatures.
